The plane, a Continental Connection flight operated by Colgan Air, was on a flight from Newark, New Jersey, to Buffalo with 44 passengers and four crew on board when it crashed in the Buffalo suburb of Clarence Center amid rain and sleet, the Federal Aviation Administration (FAA) said.
Erie County Executive Chris Collins said all 48 people on board Continental Airlines Flight 3407 were killed. One person was killed in the house while two others escaped with minor injuries, he said.
"At this point there is no information whatsoever as to what the cause may be," Collins told a news conference early on Friday. He said the control tower lost contact with the plane before it landed but officials knew of no trouble.
Clarence Town supervisor Scott Bylewski told reporters: "I did hear what sounded like a door slamming ... I then went outside of my own house and could see that the sky was red."
"It's remarkable that it only took one house, as devastating as it was. It could have easily wiped out that whole neighborhood," Dave Bissonette, emergency coordinator for the town of Clarence, said.
"The only recognizable piece of the plane left is the tail," he said.
Colgan Air said the plane was a Bombardier Dash 8 Q400. The plane is a turboprop regional aircraft that can carry more than 70 people, and is made by Bombardier Inc. Colgan Air is a subsidiary of Pinnacle Airlines Corp.
"AIR SAFETY INCIDENT"
"All indications are that this is an air safety incident," Amy Kudwa, spokeswoman for the U.S. Department of Homeland Security, said in Washington when asked about any possible terrorist connection.
Weather conditions were not unusual for that part of upstate New York at this time of year -- snow, 32 degrees F (0 degrees C), moderate wind, Bissonette said.
But because of the weather, investigators will look at icing as a potential cause. Safety experts say even a small buildup of ice on the wings can affect aerodynamics although commercial aircraft are equipped with de-icing systems.
Investigators should be able to recover the flight data and cockpit voice recorders, which could yield important information about any mechanical problems or other potential causes.
The Buffalo News quoted Niagara Frontier Transportation Authority spokesman C. Douglas Hartmayer as saying there was little communication between the plane and the tower before the crash. It said crew members on the flight from Newark Airport had reported mechanical problems as they approached Buffalo.
An aviation source with knowledge of the incident said there was no distress call from the crew |
